    Question JOptionPane with Multiple JTextFields

    Here's My code to create multiple JTextfields in a Single Option Pane.
    My goal is simple.
    Take some input from the user and then store it a TEXT File.
    The code is simple enough so i dont think it needs any commenting.

    package printer;
     
    /**
     *
     * @author Amit
     */
     
    import java.awt.Toolkit;
    import java.io.BufferedWriter;
    import java.io.FileWriter;
    import java.io.IOException;
    import javax.swing.*;
     
    public class Database {
     
    	JTextField name =  new JTextField();
    	JTextField roll =  new JTextField();
    	JTextField batch=  new JTextField();
     
            Object[] inputs = {
                "Name",name,"Roll No",roll,"Batch",batch};
    	/*final JComponent[] inputs = new JComponent[]{
    			new JLabel("Name"),Name,new JLabel("Roll No"),Roll,new JLabel("Batch"),Batch	
    		};
    	*/
     
    	Database()
    	{
    		JOptionPane.showMessageDialog(null,inputs,"Enter Details",JOptionPane.PLAIN_MESSAGE);
    	}
     
    	public void saveText() throws IOException
    	{
    		BufferedWriter out = null;
    		try{
    			FileWriter fstream = new FileWriter("C:\\Users\\Amit\\Documents\\databaseFile.txt",true);
    			out = new BufferedWriter(fstream);
    			String s = "Name: "+name+System.lineSeparator()+"Roll No: "+roll+System.lineSeparator()+
    			"Batch: "+batch+System.lineSeparator();
    			out.write(s);
                            System.out.println(name.getText());
     
    		}catch(IOException e){
    			Toolkit.getDefaultToolkit().beep();
    			//Beep signal emitted on reciept of and error
    			JOptionPane.showMessageDialog(null,"Could Not Locate Database","Error",JOptionPane.WARNING_MESSAGE);
    		}finally{
    			out.close();
    		}
    	}
     
    }


    The problem with the code is that the output in the text file is not what is want.
    I want the output to be like for eg:
    Name: Amit
    Roll No: S1070
    Batch: D

    but i am getting this in the text file:

    Name: javax.swing.JTextField[,0,19,232x28,invalid,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.synth.SynthBorder@6df16cbd,flags=288,maximumSize=,minimumSize=,preferredSize=,caretColor=,disabledTextColor=DerivedColor(color=142,143,145 parent=nimbusDisabledText offsets=0.0,0.0,0.0,0 pColor=142,143,145,editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=DerivedColor(color=255,255,255 parent=nimbusSelectedText offsets=0.0,0.0,0.0,0 pColor=255,255,255,selectionColor=DerivedColor(color=57,105,138 parent=nimbusSelectionBackground offsets=0.0,0.0,0.0,0 pColor=57,105,138,columns=0,columnWidth=0,command=,horizontalAlignment=LEADING]

    Default Re: JOptionPane with Multiple JTextFields

    That seems like an object file for one of the Swing libraries (I am not certain though). Just a quick suggestion - when you
    state the txt. file location, shouldn't it be a single '\' escape character rather than a double one '\\'? Again, only a thought.

    Looking at the file output, it does seem like the sort of code that is executed via the JVM - not really what you want.
    I am sure other can give you a better answer, thought I'd add my two cents.

    i am getting this
    That looks like the String that is returned by the class's toString() method.
    If you want the data contents of the class, you need to call one of the class's methods that will return the class's contents.
    If you don't understand my answer, don't ignore it, ask a question.

    When i check the data in the variable name by printing it to the console using System.out.println(name) i get the correct correct content.
    For example if i enter NORM i get NORM in console but In the file it is something like

    Name: javax.swing.JTextField[,0,19,232x28,invalid,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.synth.SynthBorder@6df16cbd,flags=288,maximumSize=,minimumSize=,preferredSize=,caretColor=,disabledTextColor=DerivedColor(color=142,143,145 parent=nimbusDisabledText offsets=0.0,0.0,0.0,0 pColor=142,143,145,editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=DerivedColor(color=255,255,255 parent=nimbusSelectedText offsets=0.0,0.0,0.0,0 pColor=255,255,255,selectionColor=DerivedColor(color=57,105,138 parent=nimbusSelectionBackground offsets=0.0,0.0,0.0,0 pColor=57,105,138,columns=0,columnWidth=0,command=,horizontalAlignment=LEADING]

    Have you solved the problem now? If not, please show what you expect the output to be.

    Finally Found The Solution!!!

    Earlier it was..

    out = new BufferedWriter(fstream);
    			String s = "Name: "+name+System.lineSeparator()+"Roll No: "+roll+System.lineSeparator()+
    			"Batch: "+batch+System.lineSeparator();
    			out.write(s);

    Simply changed this to..

    out = new BufferedWriter(fstream);
    			String s = "Name: "+name.getText()+System.lineSeparator()+"Roll No: "+roll.getText()+System.lineSeparator()+
    			"Batch: "+batch.getText()+System.lineSeparator();
    			out.write(s);

    And it worked...
